Yeah, although it's not such a bad idea to have one system sync'ed to the pool, and the rest sync'ed to that system.
Exactly what I'm trying to do
because
I have a STB running Linux
What is an STB?
that when configured to use a public pool always fails to sync. When setting it up to a specific public server like time.nist.gov or time.mit.edu it randomly works or not. It seems to work no more than about once or twice a day,
That sounds like a dodgy network. Fails to sync is either a) fails to connect to time-server or b) the STB is too far out-of-sync.
but typically needs rebooting multiple times a day to avoid catching video output corruption while attempting to record from it. When it fails on reboot it gets a 1999 date and 00:00 UTC time setting. I was hoping a local server would somehow be more reliable.
Do you know how it sets the date on startup? With that kind of difference, it would need to start ntp with '-g' to override the safety check. Maybe it uses sntp?
When I set the STB to sync to the local hostname or IP of my local NTP, it always fails, and the output of 'tcpdump -n -i etho port 123' never sees anything incoming from the STB,
Firewall issue?
while it is showing 140.99.51.114.123, which I would think my router should be blocking. Or could that be an IP via us.pool.ntp.org?
It could be, yes. 140.99.51.114 = tuppy.intrepidhosting.net.
I have no idea how the STB actually gets the date from the internet. It has no ntp command, no ntpd command, no tcpdump command, and no /etc/ntp.conf.
sntp?
A ntp server URL is fed into the GUI UI if auto sync from internet is selected.
What does that look like? ntp://server/etc ??? -- Per Jessen, Zürich (0.4°C) http://www.dns24.ch/ - free DNS hosting, made in Switzerland. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
